OIL TRANSFER PRESSURE UNITS- From 70l/h to 1500l/h GE – twin system
GE: 2 pumps
Inpro pressure units are equipment used to transfer liquid fuel such as diesel or HVO from a main tank to different consumption points through the pressurization of a line, for the supply of machinery that requires these fuels, such as generators (power generators) or burners for boilers in buildings.
.
There are several sizes and configurations of equipment, in which the flow rate that can control the equipment can vary (from 30l/h to 12,000 l/h), the maximum pressure at which they can work, with the possibility of redundancy in some components, and other parameters such as the type of power supply.
.
It can be Normal or Twin equipment that duplicates critical components to increase reliability.
.
Application area example
Small units (from 30l/h to 1,500l/h) can be used for:
- The supply of boilers in single-family houses.
- Community of neighbors buildings
- Small installations.
And large units (from 2,000l/h to 12,000l/h) can be applied in:
- Large buildings requiring 24h/7 electricity
- Data Centers
- Hospitals
- Airports
- Malls…
Applications & Specific Features
- Multiple burner, appliances or service tanks supplied with one GP pressure unit.
- Appliances installed at different heights.
- Modulating burners when using the Inpro Oil Burner Inlet Assembly (see Datasheet).
- Oil Supply installation using ‘dead leg’ pipework. GP unit does not need external controls.
- GP units operate on an internal pressure switch only pumping fuel when required.
- Pressure regulators may be required at oil inlet to burners/appliances.
- Limited suction lift may require GP unit to be sited near the oil tank.
Accessories and Adaptations Art. Nr.
- Free voltage relay output to control from centralised Building Management System, in kit 6 signals (2-thermal,motors 1 or 2 ON, low pressure and Leak safety ON). Standard in GP 800 and GP 1500.
- GSM alarm system by SMS messages, or connection to modem.
- Adaptation of Pressure Group for high pressure, working conditions of up to 6 Kg/cm2
- Leak collector trays with infrared detectors (standard in GP-800 and GP-1500).
Modifications to adapt to specifically regulated environments with tropicalised equipment or ATEX.
